Step 1: Identify the wave number from the given wave equation. The general equation for a progressive wave is y = A( t - kx), where k is the wave number. The given equation is y = 0.1 (400 t - 20 x). By comparing the two equations, we can see that the wave number k = 20 rad/m. Step 2: Use the formula for phase difference. The phase difference between two points separated by a distance x is given by the formula: = k x We are given x = 0.05 m. Step 3: Substitute the values and calculate the phase difference. = 20 rad/m × 0.05 m = 20 × (5)/(100) = 20 × (1)/(20) = radians Step 4: Compare the result with the given options. The calculated phase difference is radians, which corresponds to option B. The correct option is B. B. radians That's 2 down. 3 left today — send the next one.
